136. Dr. Goodenowe: Plasmalogens and the Hidden Science of Longevity
Extend Podcast with Darshan Shah, MD
Most people think brain aging is inevitable. What if the real future of longevity is protecting cellular health long before symptoms appear. In this episode of Extend, we sit down with Dr. Dayan Goodenowe, neuroscientist and biochemist, to explore the hidden role of plasmalogens in brain health, aging, and all-cause mortality. Dr. Goodenowe shares how his work in advanced metabolomics revealed that declining plasmalogen levels can predict dementia, cancer recurrence, and shortened lifespan years before disease is diagnosed, reframing aging as a loss of health rather than a disease...

129. Ashley Koff: The GLP-1 Conversation Most People Are Missing
Extend Podcast with Darshan Shah, MD
Most people think weight loss is about discipline, calories, or finding the right medication. But what if the real issue is that we’ve misunderstood how hormones, digestion, and recovery actually regulate metabolism in the first place? In this episode of Extend, we sit down with registered dietitian Ashley Koff to unpack what GLP-1 medications are really doing in the body and why bariatric surgery revealed metabolic changes long before significant weight loss ever occurred. We explore incretin hormones, vagus nerve signaling, and why appetite, blood sugar, and inflammation are part of a much...

128. Hidden Environmental Toxins Are Destroying Your Health
Extend Podcast with Darshan Shah, MD
How much control do you actually have over the toxins in your daily environment? Most people assume chemical exposure is unavoidable, but the science shows there are practical steps that can significantly reduce your toxic load. In this solo episode, we break down why environmental detoxification is a key strategy for protecting your long-term health and longevity. We walk you through the main sources of exposure, from household cleaners and cookware to synthetic fragrances and clothing materials. We explore how these toxins affect your hormones, immune system, and metabolism, and why...

127. Allison Evans: Hidden Household Toxins That Are Making You Sick
Extend Podcast with Darshan Shah, MD
Toxin exposure rarely announces itself loudly, yet it quietly shapes hormone balance, immune resilience, mood, and neurological health long before a diagnosis appears. The real tension lies in the fact that these exposures are largely invisible, normalized, and happening inside the very spaces meant to keep us safe. We dive deeper into this in the Extend podcast with Allison Evans. We also chat about the “toxic bucket” concept, why synthetic fragrance and harsh disinfectants can act as endocrine disruptors and neurotoxins, how asthma, fertility challenges, and chronic symptoms can be...
info_outlineMost people think about the gut as a digestive system, yet emerging research shows it functions more like a command center shaping immunity, metabolism, mood, and even coronary artery calcification. The surprising twist is that your gut may be influencing your brain more than your brain influences your gut.
In this episode of Extend, we sit down with Dr. Steven Gundry, cardiac surgeon and world leading expert on the microbiome, to uncover how gut bacteria communicate with your mitochondria and brain, why leaky gut silently drives inflammation throughout the entire body, and how keystone species like Akkermansia help rebuild the gut barrier. We break down the role of vitamin D in activating gut stem cells, the impact of glyphosate on serotonin producing bacteria, and why pasteurized or even dead bacteria can modulate the ecosystem just as powerfully as live strains.
We also explore how gut derived signals from short chain fatty acids, gasotransmitters, and microbial messenger RNA shape mood, cognition, vascular health, and long term aging trajectories.
Dr. Steven Gundry is a renowned heart surgeon, bestselling author, and pioneering researcher in microbiome science whose work has transformed our understanding of gut driven inflammation, autoimmune disease, and the gut brain axis.
